• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc hien)) xanh - hanh doanh ((cua thong) OR (cua khong)) cong tac tran ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc hien)) xanh - hanh doanh ((cua thong) OR (cua khong)) cong tac tran ban*.
